Methods Collect information on occupational health examination and occupational disease reports for major occupational disease hazards from January 1 to December 31,2023,and organize and analyze the collected information. Results In 2023,972 enterprises in Pidu District of Chengdu conducted occupational health examinations on 17 740 workers who were exposed to occupational hazards,cumulative total of 127 kinds of occupational disease hazards,detection of suspected occupational disease 7 people,occupational contraindications 78 people. Among workers exposed to different types of dusts,2 cases,1 case,and 1 case of pneumoconiosis-like changes were detected in silica dust,welding fume,and other dusts,with detection rates of 0.43%,0.07%,and 0.01%,respectively. The detection rates of pulmonary ventilation dysfunction in silica dust,coal dust（coal silica dust）,asbestos dust,cement dust,welding fume,and other dusts were 9.64%,5.57%,13.56%,3.83%,8.67% and 11.74%,respectively. The detection rates of leukocyte,neutrophil and platelet count abnormalities in benzene-exposed workers were 3.36%,2.63% and 1.21%,respectively,and the detection rate of binaural high-frequency hearing threshold ≥40 dB in noise-exposed workers was 5.31%. In 2023,totally 12 confirmed cases of occupational diseases were reported in Pidu District of Chengdu,including 7 cases of occupational pneumoconiosis（6 cases of silicosis and 1 case of foundry pneumoconiosis） and 5 cases of occupational noise deafness. Conclusion Pneumoconiosis,occupational noise deafness are the key occupational diseases in Pidu District of Chengdu. Among the different types of enterprise distribution,manufacturing and construction are the key monitoring industries,and private and micro or small enterprises are the key control targets for occupational disease prevention and control.
